Decontamination of patient bathroom surfaces with 405 nm violet-blue light irradiation in a real-life setting
Background: Irradiation with violet-blue light (VBL), in the spectrum of 405–450 nm, has been reported to be effective against pathogenic bacteria. Aim: To investigate whether VBL irradiation could reduce the level of surface contamination at seven shared patient bathrooms in two wards at a hospital in Sweden. Methods: Repeated sampling of five separate surfaces (door handle, tap water handle, flo
